TYPE-CASTING MACHINE.

Specification of Letters Patent.

Application filed. October 13, 1915. Serial No. 55,660.

. the molds of type casting machines and has reference to molds forcasting single types whether of that character where the mold is carriedby a swinging frame or slide and opens and closes respectively asthemold recedes from or approaches the casting spout, or of thecharacter where the mold parts slide relatively one to the other to openand discharge the cast types and close fora fresh castingoperation.

The object of my present invention is to -provide means whereby a singleadjustable mold composed of two main L-shaped parts can be employed forall body sizes of type and adjustment for set width is also provided.

Another object is to provide for the easy detachment of the breaks ortangs, while a further object of the invention is to provide meanswhereby the same molds which are employed for casting character typescan also be employed for casting space types.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a rear elevational view of the molds of my machine in theclosed position. Fig. 2 is a front sectional elevation of the moldsshown in Fig. 1 from the opposite side. Fig. 3 is a sectional view online A-A of Fig. 2. Fig. 4 is a partial sectional view illustrating themold after the type has been cast and the mold has commenced to open.Fig. 5 is a perspective view of one form of complete cast type togetherwith its tang or break.

Referring to these drawings and particir larly to Figs. 1 to 5 thenumeral 1 designates the swinging frame which carries the upper L-shapedmold part, 'and the numeral 2 designates the stationary support for thelower L-shaped mold part. The upper mold part consists of a block 3 inwhich a vertically adjustable member 4 is slidably mounted and the lowermold part consists of a horizontally slidable block 5 carrying avertically adjustable member 6. To adjust for body size either themember t is adjusted to the'member 6 by means of the adjusting screw 7or the member 6 may be adjusted up to the member l. That is to say, oneof the members 4 or 6 is set to the correct position to give the desiredbody size, which can be determined by means of a gage piece 8, and theother member is then adjusted to it. To adjust for set width the block 5is adjusted horizontally by means of the screw 9, and of course carrieswith itthe member 6. When the mold is once adjusted it will be seen thatit consists of two composite L-shaped parts, one of the composite partsbeing formed by the members 3 and a and the other of the composite partsbeing formed by the members 5' and 6. ltwill be seen that the parts 4:and 6 can be adjusted in the parts 3 and 5 so that in the views such asFig. 2 the composite parts will appear L-shaped. The front ofthe mold isclosed by the tang or break mold 10 and the rear of the mold is closedby the matrix 11 in the usual manner.

The operation of the machine is similar to that of an ordinary Titchenermachine. That is to say, after the casting operation the matrix andcasting spout move away and the upper part of, the mould swings up aboutthe hinge 12. The type is carried up until its extremitiesthe characterat one end and projection left upon the end of the breakcome intocontact with some fixed obstructions on the machine and the cast typeis'thus knocked out of the mold and falls down and slides off the lowermold part, the whole mold being arranged upon an incline as shown inFig. 4- for this purpose. If this operation is performed, however, inthe usual manner, the cast types will still have the tangs or breakattached to them and they will have to be removed by hand as is usual. Ipropose howeverand it is an important feature of my inventiontoautomatically remove the breaks before the cast types are released. Toaccomplish this I provide the upper part of the break mold with anundercut recess 14 so that the types are cast with a projection 15. Asthe upper mold part rises, this projection holds the type locked to theupper mold part, and I arrange an obstacle 16 which abuts against theend of the spring controlled spindle 18 which is restricted to a verylimited movement by means of the fixed memher 19 as is clearly shown inFig. 3. This obstruction l6 is so placed that the type first comes" intoengagement with it at its character end and this serves to. detach thetype from its break-seeing that the break is still locked to the mold bythe projection 15and the type falls away in the usual manner. Thefalling type is indicated at 'I in Fig. 4. The upper mold part continuesits opening movement until the projection 15 of the break which is stilllocked to the mold part engages an inclined obstruction indicated by thenumeral 16 and the break is thus pushed sidewise to insure thedisengagement of the projection 15 from the recess 14. The break thusfalls away and the mold closes for the next operation. It will benoticed upon reference to Fig. 5 that the nick 17 is cast in the top ofthe type and the break is arranged at the bottom to facilitate thedetachment of the break from the type. The severance of the breakusually leaves a bur at the foot of the type which usually has to befiled off by hand.

Having thus described my invention, I claim- 1. A mold for type castingmachines comprising two L- haped halves each consisting of tworelatively adjustable members, means for adjusting these members wherebythe area of the mold cavity can be adjusted, and means whereby thetypeis cast with a projection on its tang by means of which it is lockedto the upper mold part.

2. In a type casting machine, an upper composite L-shaped mold part, alower composite L-shaped mold part, a hinged frame carrying said uppermold part, means whereby the type is cast with a projection on its ofthe mold cavity, at least one of the blocks being L shaped, meanswhereby relative movement of said blocks may be produced to close andopen the mold, two auxiliary blocks carried by said blocks forming twosides or" the mold cavity and adjustable in the direction of the openingand closing movement'of said first mentioned blocks, and 'means wherebyrelative adjustment of said first mentioned blocks may be made in adirection at right angles to the'opening and closing movement.

4. A mold for type casting machines com-V prising two complete L shapedhalves in closing a mold cavity of rectangular or cross section, andmeans whereby said halves may be adjusted to alter the cross section ofsaid cavity in each of two directions at right angles to each other.

In testimony whereof I afiix my signature in presence of two witnesses.
